Why Does My AC Take So Long to Get Cold?

- 11:07 am - April 18th, 2024

Feeling uncomfortably warm indoors even with the AC running? There are several reasons why your cooling system seems sluggish. Let’s explore some common culprits and potential solutions.


  • Clogged/dirty air filters: A dirty air filter is a prime suspect. It restricts airflow, making the AC work harder and longer to cool your space. Check your filter monthly and replace it as needed.

  • Dirty condenser/evaporator coils: The condenser and evaporator coils are responsible for heat transfer. Buildup of debris on these coils can hinder the efficiency of your air conditioner, so it’s important to schedule regular maintenance with us.

  • Leaking refrigerant: Refrigerant leaks can cause inadequate cooling and are dangerous for you and your family, since inhaling it is poisonous. Condensation and minimal liquid in your drip pan is normal, but if you notice excessive liquid in the drip pan, contact us immediately for professional repair.

  • Old AC unit: If your unit is old and taking a long time to cool your home, a new unit could keep you more comfortable and use less electricity.

  • Undersized AC unit: An AC unit that’s too small for your home simply won’t be able to keep up with cooling demands.

  • Improper thermostat settings: Setting your thermostat too low will cause your AC to work harder than it should, keeping your home uncomfortably warm and increasing your energy bills.
